This spell inhibits or otherwise distracts its target by inducing lapses of concentration or subtle blocks in the mind, lengthening the activation time of its special abilities. The target must make a Will save every time they attempt to cast a spell, manifest a power, use a maneuver or invoke any sort of other special attack. If they fail the save, the special attack becomes stifled.

Abilities that use either free actions or that take one round or more to use are unaffected.

This spell persists regardless of successful saves, and only ends when the duration expires. However, an unsuccessful caster level check against the target creature's spell resistance negates the spell entirely.
